摘要： Methods, systems, and articles of manufacture are provided for manipulating partitions while imaging them to another disk on the same or another computer. By integrating partition manipulations with imaging, the invention reduces data movement. Rather than resizing a source partition in place and then imaging the resized source partition, for instance, one embodiment of the invention leaves the source partition intact and performs resizing on-the-fly by manipulating a memory-resident copy of the source partition's file system structures and then copying the modified structures and corresponding portions of the source user data to the target location. In addition to partition resizing, on-the-fly manipulations possible with the invention include cluster resizing, defragmentation, file relocation, and others. Novel image file formats suitable for on-the-fly manipulations are also described.

摘要： Methods, systems, articles of manufacture, and signal formats are provided for transferring disk images from a transmitting computer to one or more downloading computers. The transfer is done in a manner that allows a technician to start the download to one computer while preparing a second computer for downloading or shutting down a third computer after it has finished downloading the disk image. The computers need not wait for the beginning of a data stream but can instead join the download at specified points within the data stream. This reduces the time spent waiting to begin the download, particularly when the disk image being transferred is large. Compression and connection selection may be performed in response to changes in network performance. Image file packing and error management techniques may also be used, as well as on-the-fly file system instance manipulations.
